That's a huge number but it's not an entirely far-fetched dream, if you look at the market potential. As seen in this chart by Statista, China's retail e-commerce sales are growing at a mind-boggling pace: It's forecast to become worth $840 billion by 2021, almost double the estimated size of the US e-commerce sales in the same period ($485 billion).

Add that to the fact that China has a massive 300 million-plus middle-class population and a growing appetite for foreign products (cross-border sales in China is expected to surpass $150 billion by 2020), and Trump-Alibaba's one million job creation goal starts to sound plausible.
